You can activate dynamic debugging for the xhci_hcd module Remember that no data to transfer is not an error as such. > My current assumption is that the signal quality of the USB port is at a > corner case, and therefore some "better" Adapters work, some "bad ones" > don't. But as there is no error message seen in the dmesg, i am somehow lost. Two things you can do: 1. Generate a usbmon trace (it will be gigantic though) 2. Activate dynamic debugging for the xhci_hcd module Regards Oliver
